A user input device has a body portion extending from a first end to a second end and having a plurality of keys, for example keys that may be arranged and configured to be a keyboard, and an optical motion element. A wireless transmitter transmits data entered through the keys to a target component, for example a computer, a PDA, a digital watch, and the like. The user input device may include a hinged panel having some of the keys, and when the hinged panel is in an open configuration, the arrangement of the keys may be similar to an alphanumeric keyboard. The optical motion element may be an optical mouse for controlling a cursor on a display, when the hinged panel is open. When the hinged panel is closed the optical motion element may be configured to serve as a digital pen, for sensing natural writing, pen motions used to control a display, such as cursor location or to make selections on a menu, for example. The device may be sized so as to be easily portable, fit inside a pocket, and may be formed to have a shape similar to a writing instrument.
A user input device comprising:
A user input device comprising a body portion movable between a first position and a second position having a first side portion and a second side portion, a plurality of keys on the body portion for entering information into the device, an optical motion element operable as a first mode of input when the body is in the first position and operable as a second mode of input when the body is in the second position, wherein the second mode of input of the optional motion element comprises a digital pen, the optical motion element being on the first side portion and configured to detect relative motion between the body portion and an adjacent surface, a processor for receiving signals from the plurality of keys and a data transmission element associated with the body portion for receiving data from the processor and transmitting signals representing the information entered into the device.
